Embodiment 1

[0037] Example 1 Indoor toxicity determination of the insecticidal composition of chlorantraniliprole and ecdysone to diamondback moth larvae

[0038] Preparation of liquid medicine: firstly dissolve the original medicine with acetone, and then dilute with aqueous solution containing 0.15% Tween 80.

[0039] Leaf soaking method (proposed by the International Resistance Action Committee IRAC): with a certain concentration of the drug solution to be tested, use straight tweezers to pick up fresh cabbage leaves, soak for 10 seconds, take out and shake off the remaining liquid, and dry at room temperature , spread in a 3cm petri dish pre-loaded with 1% agar (3cm thick), put 1 piece in each dish (2 / 3 of the petri dish is equivalent). The test was set up with 6 concentrations of pharmaceutical treatments (that is, the concentrations were 10, 25, 50, 100, 250, 500ppm respectively), and each treatment was repeated 3 times;

[0040]In addition, the leaves of head cabbage were soaked i...

Abstract

The invention belongs to the technical field of pesticides and discloses an insecticidal composition containing butyl chlorantraniliprole and a molting hormone. The insecticidal composition comprisesan active ingredient A and an active ingredient B at a weight ratio of (50-1):(1-50), wherein the active ingredient A is butyl chlorantraniliprole; the active ingredient B is one of tebufenozide and dibenzoyl-1-tert-butylhydrazine. The composition can be prepared into various agriculturally allowable dosage forms, has a better effect on prevention and control of homona coffearia, rice leaf rollers, diamondback moths and the like, and can effectively retard resistance generation of pests; compared with a single preparation, the composition has a good prevention and control effect, is good in fast-acting property and persistence, and has an obvious synergetic effect; an insecticidal spectrum is enlarged.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to an insecticidal composition containing chlorantraniliprole and ecdysone and a preparation thereof. Background technique [0002] A new type of insecticidal compound - polysubstituted pyridylpyrazole amides has been published in a Chinese patent application with application number 201410190515.2 and titled "Polysubstituted pyridylpyrazoleamides and their preparation methods and uses". The preferred compound in the compound of the general formula is named by the National Pesticide Standardization Technical Committee (2017) Agricultural Standard No. 048 file named "Chlorantraniliprole", chemical name: 3-bromo-N-(2-( tert-Butylcarbamoyl)-4,6-dichlorophenyl)-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-benzamide, the structural formula is as shown in I: [0003] [0004] Chlorantraniliprole belongs to the amide insecticide, it activates the ryanodine receptor in the muscle of the pes...
